BRICK Filed July 30, 1932 INVENTOR. CLA/PE/VC'E/P/VSTI/K TTO NEY.

Patented Oct. 22, 1935 UNITED STATES PATENT OFFICE 1 Claim.

My invention relates to bricks and is particularly directed to cornerbrick used with facing brick in building construction and the like.

This invention is especially intended for use 5 with face brick of thetype shovm in my copending application Serial No. 550,336 filed July 13,1931.

The extended commercial adoption and use of face brick in place of theold full size brick for building purposes created a problem inconnection with the use of brick for corners which would conform to, inpoint of space occupied, and appearance, the face brick used in the flatwall surfaces. To use a full size brick at the corners of a structurewhere facing brick was used for the wall surfaces in order to secure theproper full width appearance at such corners, meant the projectioninwardly from the rear surface of the corner of approximately half ofthe width of the brick. This was objectionable because frequently facebrick are used to cover over an old structure, perhaps of woodconstruction, and the space between the wall and the narrow face brick,

would not permit the use of a full sized brick at the corners.

To meet this problem I have provided a corner face brick which requiresno more lateral space than do the narrow wall face brick and which canbe made in the process of manufacture to conform in all respects to theappearance as regards surface, of the wall face brick.

My invention embodies not only the corner face brick itself but themethod and apparatus for making the same.

Various objects and advantages in details will be apparent as thedescription proceeds, reference now being had to the figures of theaccompanying drawing forming a part of this application and wherein likereference numerals indicate like parts.

In the drawing:

Figure 1 is a side view of a portion of my improved brick makingapparatus illustrating one stage in the method of manufacture.

Figure 2 is a front view of the expressing and trimming dies throughwhich the plastic brick material passes.

Figure 3 is a perspective view of a completed brick according to thisinvention, before separation for use.

Figure 4 illustrates the corner face brick with the section removed toadapt it for the purpose intended.

Figure 5 is a detail perspective view of the completed brick in adifferent position from that shown in Figure 3, namely, in the positionand condition in which it passes through the die in strip form.

Figure 6 is a detail perspective view illustrating the use of cornerface brick under actual conditions of construction.

The reference character I refers to a suitable container for the plasticbrick material supplied by any suitable apparatus for mixing and forcingthe plastic material therethrough. One end of m the container I isflanged as at 2 and removably secured to the flange as by the bolts 3 isthe flange 4 of an expressing die 5 provided at its front end with aflanged plate 6. The die 5 is provided with a passage 1 therethroughwhich at the plate 6 1 defines the approximate size and shape of thebrick to be formed, by the opening 8. This passage is wider at the rearend of the die 5, the side walls of the opening diverging rearwardly asat 9 so that at the point of communication with the discharge end of thereceptacle 1, such passage is relatively large and then tapers down tothe size of the opening 8.

Suitably provided, preferably integral with the sides of the die member5 and centrally of the passage 1 therethrough and adjacent the point ofcommunication with the end of the recess l, is a supporting bar H] towhich is secured a member ll carrying a plurality of forwardly extendingpins [2, in the instance here shown, 3 of such pins, which pins projectthrough the passage 1 to a point just beyond the opening 8 in the plate6, for a purpose to be described.

A ribbon of plastic brick material I3 is forced by any suitable meansthrough the die 5 and outwardly through the opening 8 in the front endthereof on to a moving belt 14 preferably of an endless character,trained over a pulley wheel 15 and driven by any suitable means. Thisconveyor belt it may be supported at various points throughout itslength as by additional idler rollers l6 mounted in suitable frames l1.

Secured to the front of the plate 6 as by screws l8 and stretchingvertically on such plate across the ends of the opening 8, are thetrimming wires l9 and 20. These wires are positioned just inside of theends of the opening 8 whereby to trim off the extreme ends of the ribbonof plastic material l3 as it is expressed through the opening 8 and onto the conveyor belt 14. These trimming wires perform the twofoldfunction of trimming the ends of the plastic material to exact size andalso of providing the sides of the plastic material passing therethroughwith the desired texture or a mat finish desirable in bricks of thistype.

Likewise secured on the front of the plate 6 as'by the screws 2| andextending across the top of the opening 8 is a third trimming wire 22 sopositioned as to trim off the top of the ribbon of plastic material alsofor'the purposes of governing size and providing the mat texture finishfor the completed brick. The thin trimmings of the plastic material fromthe ends and top of the ribbon l3 may be guided away from the die andfrom the ribbon in any suitable manner, these trimmings being removedentirely from the plastic material.

In order'that these corner facing bricks may be of the same width orthickness except at one end; as the wall face brick such as-describedand claimed in the above mentioned'copending ap-" ''plication, a fourthwire 23 is provided, secured at one end to screw 24 on the plate 6 andat the other end to-the end of one of the pins l2 extending through thedie 5 and outwardly through v the opening 8. The selection of the pin l2to which the inner end of the'wire 23 is attached depends upon the sizeof the portion of the brick it is desired to cut by this wire 23. 'Stillanother wire 25 is secured at one end by the screw 26 on the plate 6 andextends vertically and in parallel relation to the wire. 20 and issecured 'at'its opposite end to the same pin l2 to which the Wire 23 isanchored. Obviously therefore, as the plastic material I3 is expressedthrough the die and through the opening 8, the wires 23 and 25 cutthesame, the wire 23 cutting the ribbon of plastic material substantiallycentrally for a portion of the length of the opening 8 and the "wire 25cutting the ribbon vertically at a point spaced from one end of theopening 8,, these two cuts joining at the opening 21 provided by the pinl2 as the material is pressed through the die.

It will be obvious, of course, the wires 23 and 25 may be a singlelength wire merely turned around the pin l2.

It will thus be seen that by thismeans the horizontal and vertical cutsmade by the wires 23 and 25 define a portion of the brick which 7 iseventually to be removed before use, as shown clearly in Figures 3 and5, leaving a brick of the shape shown in Figure 4 for use at the comersr of a building construction. The pins I2, of course,

all provide the openings 21 through the brick V 6 material whichfacilitates subsequent separation of the section to'be removed andwhich, of course,

i do not interefere with the appearance of the brick inasmuch as theseopenings are on the inside surface in use, as shown clearly in Figure 6.r

The ribbon of plastic material l3 after being so cutby the wires 23 and25 moves alongwith the conveyor l4 as before described and due topending upon the size of brick desired and these are then baked orotherwise hardened to form the finished product. When the bricks areready.

for use, merely tapping the section defined bythe cutting operation ofthe wires 23 and 25 serves to remove such section leaving the brick asshown in Figure 4. V

7 By reversing the position of such brick alternately as the corner of awall is built up, it

will be seen that the outside appearance is that 01' a fullsized brickwhile as a matter of fact the corners are of the same thickness as the2Q narrow face brick'used in the. wall surfaces;

The removable section of the brick has been esignated at 28 and theportion used in actual construction indicated at 29. By my process thesesections are left intact with their cut surfaces 25 adhering togetherduring all the steps of manufacture and transportation to the pointof'use which serves as a protection to the corners and edges and greatlyreduces loss through breakage, etc.

r 30 It will also be noted that by virtue of the trimming wires I9, 20,and 22, the surfaces of the corner face brick which are exposedare ofthe same texture and mat finish as the wall face brick as manufacturedin accordance with said copending application Serial No. 550,336.

Of course, changes and modifications may be made by way of detailwithout departing from the spirit and scope of my invention. I do notshown and described other than by the appended claim.

I clalm: r A corner facing brick comprising a substantially rectangularblock having a cut through its body for a portion of its length and asecond cut at an angle to and intersecting said first cut, the portionsof said block divided by said cuts adhering together and being separableby tapping, one of said portions extending from a point spaced from oneend of said block and from substantially half the width thereof, for therest of the length of the block and leaving a substantially L shapedcorner facing brick.
